2002 Chrysler PT Cruiser 2.0L need spark plug gap for Champion copper plugs (470). Thanks
It is normal for the electrodes to
wear as the plugs age. This increases the distance between the
electrodes which in turn leads to a gradual increase in the firing
voltage required to jump the gap. The gap on a standard spark plug grows
about 0.00063 to 0.000126 inch for every 1,000 miles of normal driving,
which means the firing voltage requirements creep up about 500 volts
for every 10,000 to 15,000 miles of driving.
The OE Champion plug gap
specifications are .048 - .053" or 1.24 - 1.37mm. in accessing and
changing the plugs on the PT. They have the same gap specifications as
the OE plugs. Most owners gap at .050. We prefer to use the Champion
Double Platinum plugs, which are more durable, provide extended plug
life, and reduce the need for maintenance, given the difficulty
However, if you experienced excessive rough idle with your last set of
plugs we suggest gaping the OE and DP plugs to .042 and consider
replacing the OE plug ignition wires.
Excessive gap can cause performance
and drive ability problems, including hard starting, an engine miss and or
hesitation under load, and can shorten the life of the plug
(accelerated tip erosion). If it were me I would re-gap them to the
correct specs if they are currently gaped at .060.
Thank you for using Fixya.
